Digital BW, The Print

An Epson native printer driver resolution is 720ppi. But you only get that
resolution when you select "finest detail" in the driver setup, otherwise
you get 360ppi.  You can test this with the test images here

Images with high frequency data (think cacti spikes) show a clear difference
printed at 720 vs 360.
